The, present invention relates to a window construction and more particularlyto one. in which a special member is inlaid into a surface of a window sill. f

Modern window constructions often include .windowframe elements including 'a relatively wide-sill member extending into the room'fr'om the sash or sash frame. Where this silli's formed of. steel, even though painted, there is a tendency for it to corrode due to water which may come through an open ventilator, or which may result from condensation at the room side of thefventilator. According to the present invention the sill-memberof the casing is provided with an inlaid member formed. of linoleum, asphalt tile, or othercorrosion resistant material. The inlaid member not only prevents corrosion of the casing sill but-also provides'an attractive appearance. If desired, theinlaidmember .may simulate marble or thelike. i v.It is an object ofthe present invention to provide in a window construction, a sill member having securedthereto a separate inlaid member. formed of corrosion resistant material. .It isafurtherobject ofthe present invention to provide. a sill. member having an upstanding flange along itsroom side edge and provided with a corrosion resistant. inlaid member abutting the flange alon one edge.

,It is a further objectof the present invention to .pr ovide a window construction comprising a sill memberhavingan upstanding flange along its,.r oom.side .edge and .a sash frame. bar adjacent itsweather side edge in combination. with a jamb construction, the lower edge of which engages .the surface of the sill member andform, together .with the flange. and sash .frame bar, sidewalls of a recessed seat at thenpper surface of the, sill member, in which a corrosion resistant inlaidmemberis provided. H n QOtherobiects andfeatures of the invention will become apparent, as the description proceeds, especially, whentaken in conjunction with the accompanyingdrawings,'wherein: I Figure 1 is .a perspective view of a window construction incorporating the present inventior I i I Figure 2 is a fragmentary section on the line 2 2,,Figurel.

Figure 8 is a view similar to Figure 7' showing a modified construction.

Referring now to .the drawings, the invention is illustrated as applied to a casement type wine dowconstruction. The window openingin the wall is framedby a casing construction;'ricluding a sill" member ID, jamb members l2, -and a top or head casingmember l4. Mounted-within the opening framed by the casing members flfl, I 2, and I4, is a ventilator frame includinga sash frame sill bar It, vertical sash frame bars I8, and head bars (not shown). Within the sash frame are-mounted swinging ventilator 1;: Referring now to Figure 4 the casing sill mer n: ber lllisformed of sheet metal, preferably steel, and includes an upstanding flange indicated generally at 22, at its room side edge, which extends above the relatively depressed portion "2301 the sill member. Below the flange 22 the casing sill includes a depending portion 24 and an, intiirned portion 25 which is adapted to serve as a plaster stop as best illustrated inFigure 2. .The flange 22 includes an inclined wall 2 8..for a purpose which will presently appear. The casing'isillj lfl cooperates with the jamb members l2 asjbest seen in Figure 4. For this-purpose the .jamb members l2 are of less width thanthe sill mem ber by an amount substantially equal 'to'. the width of the flange 22. The lower edge -of the jamb members [2 abut against the upper surface of the depressed portion 23 of the sill member and are interlocked therewith by tabs 30, which extend through correspondingly positioned slots provided in the sill member and which are thereafter bent overas indicated in Figures 2 and}, Adjacent its weather side edge. the sillcasing It] has secured thereto the sash frame sill bar 16. Therefore the depressed. portion 23 ofthe casing sill member issurrounded at the room side by thefiange 22, at. the ends by the'casing iamb members [2, and at the weather side by the sash frame sill bar 16. These members together define a recessed seat located at. the upper surface of the casing sill member. This seat is provided with a corrosion resistant inlaid member 32. Preferably, the inlaid member is formed of a separate sheet material' such for example as linoleum, asphalttile, or thelike. If desired, it may be in the form of a suitable plastic or non-ferrous material either initially formed into a sheet material and precut to within the recessed seat, or applied thereto in plastic form and allowed to harden or settherein. In practice, excellent results are obtained when the inlaid member is formed of linoleum. iIIH order to retain the inlaid member. in position, suitable adhesive-isprdvided whichl'is coextensive with the bottom and edge surfacesof theniemher and which not only retains the member firmly in the illustrated position, but which also serves to prevent the entrance of water at the edges of the member. The edge of the member 32 along the room side thereof may be beveled to cooperate with the inclined wall 28 of the flange 22, thus providing a firm mechanical interlock to retain the member in position.

In many cases it is desirable to ship the casing members and sash frame members disassembled and to assemble them into the casing frame and the sash frame on the job. Where thi is done it is of course desirable to first assemble the sash frame sill bar I6 to the casing sill member ID, after which the member 32 is adhesively applied to the casing sill member. Application of the member 32 to the casing sill member ID may take place either before or after assembly of the casing sill member with the casing jamb members Referring now to Figures 5-8 there is illustrated additional modifications of the same invention. As seen in Figures 5 and 6, the window construction comprises a broad sill having a portion 42 extending outwardly beyond the room side wall surface 44. The window opening in this case is illustrated as provided with the plaster return type construction, the corner 46, the Window opening surface 48, and the wall surface 44 being plaster when casement type windows are provided. The sill member 40 is formed of metal and the portion which extends into the room beyond the inner surface of the wall a l is formed to provide an upwardly extending portion such as a bead or flange 52, beyond which there is a broad flat surface 54. The casement window 50 in this instance is illustrated as adapted to weather directly against the weather side of the sill frame bars 56. The broad flat surface 54 of the sill is covered with an inlaid sheet member which may be of corrosion resistant material such for example as linoleum or the like as previously described. The room side edge of the sheet member abuts and partially underlies an inclined in-' ner surface of the bead or flange 5 2 in the same manner as shown in Figure 2.

In Figure 7 there is illustrated a modification of the sill illustrated in Figure 1. In this case the sill member includes an upstanding head 61 extending into the room beyond the plaster 62. Toward the weather side of the sill member 60 there is a broad fiat depressed portion 63 which receives the sheet member 64 formed of corrosion resistant material, In this construction the sill member 60 at its weather side is formed to cooperate with and provide a surface against which the ventilator sill bar 65 weathers. Itwill be appreciated that in this construction the jamb and head members which cooperate with the sill member to encase the window opening, are similarly formed to cooperate with the corresponding jamb and head members of the ventilator frame.

- Referring now to Figure 8 a somewhat modified construction is provided. In this case the sill member in addition to an upstanding flange or bead 10, at its room side, is provided with a similar upstanding flange 12 adjacent its weather side against which the sill bar '14 of the ventilator 16 is adapted to weather. The flange or bead i0 and the flange 12 together define side walls of a depressed central portion 18 of the sill member which is completely covered by the inlaid corrosion resistant sheet member 80.

In cases where the sides of the window opening are closed by the plaster return type of construction the sill member may if desired be provided with an inlaid sheet member such as which extends under the plaster. Alternatively, the inlaid sheet member may be applied after the plaster has been finished in which case it will abut the finished plaster at its ends.

The plaster return 'type of construction has been specifically illustrated but it will be readily appreciated that the invention is equally applicable to other types of window constructions such for example as where a wood casing is applied to surround the sides and top of the window opening.

The essential feature of the invention is in the provision of a sill member formed of metal and having a depressed seat in which is provided a corrosion resistant sheet material adapted to provide a finish surface for the sill. The metal sill is constructed and arranged to protect the inlaid material and to provide an attractive appearance for the assembly. r

The drawings and the foregoing specification constitute a description of the improved inlaid surface for awindow sill in such full, clear, concise and exact terms as to enable any person skilled in the art to practice th invention, the scope of which is indicated by the appended claims.

What I claim as my invention is:

1. In a window construction having spaced vertical jamb surfaces at opposite sides of a window opening and a ventilator at the weather side of the opening, a window sill formed of sheet metal and extending inwardly from the ventilator beyond the room side edge of said jamb surfaces, the room side edge of said sill being formed into an upwardly extending bead the weather side edge of which is substantially in the plane of the room side edge of said jamb surfaces, acorrosion resistant sheet member adhered to the fiat upper surface of said sill and abutting said bead and covering substantially the entire surface of said sill between said bead and the ventilator, and between the jamb surfaces.

2. Structure as defined in claim 1 in which said sill has an upwardly extending fiange at the weather side thereof against whieh the weather side edge of said sheet member abuts.

3. A window frame construction comprising a broad sill member having an upstanding narrow flange along its room side edge, jamb members having inner surfaces at the bottom thereof in-. tersecting the upper surfaces of said sill member at the ends thereof and at the weather. side of said flange, an upwardly extending elongated element extending. along said sill at the weather side thereof, said flange, the inner surfaces at the, bottom of said jamb members, and said element defining a completely surrounded recessed seat on said sill member, and a corrosion resistant sheet member covering said entire seat and adhfiled thereto.
